Here, we report the selective, catalytic isomerization of cis-1,2-diols to trans-diequatorial-1,2-diols. The method employs triphenylsilanethiol (Ph3SiSH) as a catalyst and proceeds under mild conditions in the presence of a photoredox catalyst and under blue light irradiation. The method is highly chemoselective, broadly functional group tolerant and provides concise access to trans-diol products
在这里,我们报道了顺式-1,2-二醇选择性催化异构化为反式-双赤道-1,2-二醇。该方法采用三苯基硅烷硫醇(Ph 3 SiSH)作为催化剂,并在光氧化还原催化剂存在下和蓝光照射下在温和条件下进行。该方法具有高度化学选择性、广泛的官能团耐受性,并且提供了使用其他方法不易获得的反式二醇产物的简洁途径。机理研究表明,异构化是通过硅烷硫醇催化剂介导的可逆氢原子转移途径进行的。
